thebar 28,V and its lovver end resting upon the sleeve 25. Normally, thecloset seat 3l occupies the position illustrated in Fig. l of thedrawings, but when depressed the rear slightly projecting armor lever 32secured thereto and which rests against the front end ot the rod 15a,causes longitudinal movement ot the latter toward the rear, so as tocause the valve 15 to Contact with the plate 13 and close the valveopening 14. Simultaneously, the bell crank lever is rotated about itspivot 2l so that its rearwardly extending arm 23 is raised. The saidaiin contacting with the lower side of the sleeve 25, causes upwardmovement thereof against the tension ot the spring to lii'ft the rod -land the valve 10 to open the latter, so that Water .may pass through thesupply pipe -l and through the valve l0 into the flush tanl: rlfhe seatis caused to return to the position indicated in Fig. l, by the actionoi the spring 230, which acting 'through the sleeve 25 upon the lever 20causes Vcotations 'of the latter and consequent outward oi' torvvardmovement of the rod 15"; ln this ivay, the valve 10 is closed,'while-tbe valve l5 is simultaneously opened. iing oi the latter i'alvepermits the vfhich has entered the flush tank 5 tloiv rapid y doivn theupper portion of the supply pipe l and through the branch pipe ll andthe coupling pipe l2 into the closet bowl or hopper to flush and cleansethe intermediate the ends of the said rod one arin oi the said leverextending at right angles to said rod and being in engagement therewith,a branch pipe having connection with the said supply pipe the saidbranch pipe having plate extending across the same such plate beingprovided with an opening, a longitudinally movable rod extendinglongitudinally ot said branch pipe and beiiigsupported therein andthereby, the said rod being provided with a valve which is adapted toopen and close the opening inthe said plate and the rear end of' thesaid rod occupying a position in operative relation to the other arm orpsaid bell crank lever, and means for effecting longitudinal movement ofthe said longitudinally movable rod substantially as and for the purposedescribed.

2. The combination ot a supply pipe, a valve for opening and closingsaid pipe said valve haring connection With rod extending longitudinallyot the said supply pipe, means for holding the said rod normally indepressed position to close the said valve, an angular lever pivotedindeliiendently ot and Atermediate the ends of said rod and having oneot its .arms extending transversely ot the said rod and in engagementthei'ev-fitli, a branch pipe extending laterally from the said supplypipe `and having a plate extending transversely thereol ivh ich plate isprovided with an opening, a rod supported by and extendinglongitudinally in the said bran li pipe said rod being provided with avalve tor closine' the opening in the said plate and the inner rear endot' the said rod being in operative rela-- tion to the other ai'ni ofthe said angular lever, and means upon the closet seat of the apparatusfor contacting with the liront end ot the said longitudinally movablerod vvhen the seat is depressed to occasion rearward longitudinalmovement o't the said rod to thereby occasion pivotal movement of thesaid angular lever to litt the rod in the said supply pipe substantiallyas and for the purpose described.
